Hydrangea arborescens plants

Hydrangea arborescens
The inflorescence is a corymb up to 15 centimetres (5.9 in) wide. Showy, sterile flowers are usually absent or if present they are usually less than 1 cm in diameter on the edge of the panicles.
Flowering occurs May to July. Fruit is a ribbed, brown capsule about 2 mm long. Many are produced in October and persist through the winter.
The leaves are large (8 to 18 cm long), opposite, serrated, ovate, and deciduous. The lower leaf surface is glabrous or with inconspicuous fine hairs, appearing green; trichomes of the lower surface are restricted to the midrib and major veins.
